Nugent-Hopkins suffered the injury after blocking a shot during the second period of Edmonton’s 4-2 victory over the Florida Panthers on Monday. McLellan told reporters after the contest that the 22-year-old Nugent-Hopkins would be sidelined "long-term" before putting a timetable on it on Tuesday.

Nugent-Hopkins has collected eight goals and 22 assists this season, with his 30 points putting him third on the team behind Taylor Hall (45) and Leon Draisaitl (35). The top overall pick of the 2011 draft, Nugent-Hopkins has scored 73 goals and set up 145 others in 304 career contests – all with the Oilers.

Edmonton (19-23-5), which resides in last place in the Western Conference, will play the second contest of its three-game road trip on Tuesday against the Tampa Bay Lightning (24-17-4).
